Trioxsalen is a very strong medicine that increases the skin's sensitivity to sunlight. In addition to causing serious sunburns if not properly used, it has been reported to increase the chance of skin cancer and cataracts. Also, like too much sunlight, PUVA can cause premature aging of the skin. Therefore, trioxsalen should be used only as directed and it should not be used simply for suntanning. Before using this medicine, be sure that you have discussed its use with your doctor.
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Although there is no specific information comparing use of trioxsalen in children with use in other age groups, this medicine is not expected to cause different side effects or problems in children than it does in adults.
Many medicines have not been studied specifically in older people.
